From page 160...
... These three rock types make up nearly 93 percent of the total volume of cratonic platform sediments, the remainder being mostly volcanics and evaporites. Geosynclinal Sediments Geosynclinal sediments, occupying elongate regions of the Earth's continental crust, usually represent sites of thick sediment accumulation on passive or active continental margins subsequently exposed by uplift and erosion as a result of plate tectonic processes.
